Laser beams in semiconductor industry
At Carbospacetech we invented a Rotating Wedge for applications that require laser beams to be aimed at distant targets. In particular we designed this compact, robust and economical device for beam steering, being used in the semiconductor industry at Hensoldt.
The CST Rotating Wedge is based on a Risley prism. The beam deflection is only dependent of the rotation of prisms around the optical axes which is measured directly and highly precise. The system is therefore resistent towards positioning in the beam path as well as external influence such as temperature or vibration.
